Music can be a motivator/cheer you up. When I exercise I always make sure that I have some of my favorite music handy to make it more bearable/pass the time (since I'm not a fan of exercising). When I'm surfing the net, I like to have music going in the background because it helps keep me calm and makes me feel better after a bad day. Of course, it depends on what type of music a person listens to. I'd lose all motivation if all I could listen to were rap and heavy metal. I'd much rather listen to J-Pop or something uplifting when I listen to music.
